SYNOPSIS

DESCRIPTION

The posix_spawnattr_getflags() function shall obtain the value of the spawn-flags attribute from the attributes
object referenced by attr.

The posix_spawnattr_setflags() function shall set the spawn-flags attribute in an initialized attributes object
referenced by attr.

The spawn-flags attribute is used to indicate which process attributes are to be changed in the new process image when
invoking posix_spawn() or posix_spawnp(). It is the bitwise-inclusive OR of zero or more of the following
flags:

These flags are defined in <spawn.h>. The default value of this attribute
shall be as if no flags were set.

RETURN VALUE

Upon successful completion, posix_spawnattr_getflags() shall return zero and store the value of the spawn-flags
attribute of attr into the object referenced by the flags parameter; otherwise, an error number shall be returned to
indicate the error.

Upon successful completion, posix_spawnattr_setflags() shall return zero; otherwise, an error number shall be returned to
indicate the error.
